抄録 In order to investigate the frequency of postgastrectomy syndrome in patients with benign gastroduodenal diseases who gastrectomized partially, the authors studied the case records of consecutive 100 such patients treated at this institute. The results obtained were as follows. 1) Concerning postoperative diagnosis, 55 patients were diagnosed as ulcus ventriculi; 22, ulcus duodeni; 4, ulcus vent. et duodeni; 10, gastric hyperacidity only; 4, perigastric adhesion; 2, ptosis ventriculi; 2, gastric polyp; 1, duodenal diverticulum. 85 patients were male; 15, female. Concerning operative method, 21 patients were operated on Billroth I procedure; 19, Billroth II antecolica oralis inferior with Braun's anastomosis; 60, Billroth II oralis inferior. 2) Of 28 patients with postgastrectomy syndrome, 9 patients had early postprandial syndrome; 6, late postprandial syndrome; 6, postoperative gastric atonia; 2, afferent loop syndrome; 1, obstruction of efferent loop; 2, intestinal adhesion; 2, ulcer of anastomosed site. 3) In our series, there were no significant difference in frequency of postgastrectomy syndrome between B. I and B. II procedure, but postgastrectomy syndrome of patients with B. II were more severe than that of patients with B. I. 4) Of 72 patients without postgastrectomy syndrome, 69,7% (50 patients) continued to gain weight postoperatively, but of 28 patients with postgastreetomy syndrome 28,5% (8 patients) gained weight postoperatively.

タイトル(別表記) Causes and Prevention of Intestinal Adhesions Part 2. Experimental Study of Intestinal Adhesions
フルテキストURL pitsr_031_054_074.pdf
著者 大谷 満|
抄録 The experiments were designed (1) to investigate the effects of various types of injury to the peritoneum on the formation of adhesions, and (2) to study the hitological changes of the intestinal wall when injured artificially with 5 % iodine tincture. The experimental animals used were Wistar adult male rats with a weight range of 90 to 120 grams. A total of 170 rats were used. Experiment 1. The experimental animals were divided into 10 groups, each group consisting of 10 to 20 rats. Group A. The caecal serosa was injured with 2 % iodine tincture. Group B. The caecal seroSa was injured with 5 % iodine tincture. Group C. The caecal serosa was abraded with gauze until subserosal petechies were produced. Additional trauma to this area waS inflicted with 2 % iodine tincture. Group D. The caecal serosa was injured as in group C, but 5 % iodine tincture was used. Group E. The caecal serosa waS injured with 2 % aqueous mercurochrome solution. Group F. The caecal serosa was rubbed with gauze until subserosaI petechies were produced. Additional trauma to this area was inflicted with 2 % aqueous mercurochrome solution. Group G. The caecal wall was rubbed with gauze 100 times, injuring the subserosa. Group R. The anterior wall of the stomach and caecum was traumatized with a toothbrush and 2 ml of aqueous talcum solution were instilled into the peritoneal cavity. Group I. Excisions of the parietal peritoneum were performed with a surgical knife over areas of varying sizes at both sides of the operation wound. Group J. Adjacent loop of the intestines with normal serosa were connected to one another by No.2 black silk suture at two or three points. In five cases of this group, contacting surfaces of the intestines were injured with 5 % iodine tincture. The results obtained were as follows : (1) Local administration of 2 % iodine tincture and 2 % aqueous mercurochrome solution would not produce adhesions unless mechanical injury, such as rubbing with gauze was also present. (2) When the serosa was slightly injured with gauze, fibrinous adhesions were separated or torn apart by bowel movements. (3) Local administration of 5 % iodine tincture produced in all members of group B. The adhesions were moderate, not extensive in degree. Additional mechanical trauma aggravated the adhesions caused by bacterial contamination. (4) Intraperitoneal instillation of 10 % aqueous talcum solution produced extensive adhesions. The favorite sites of occurrence of the adhesions were the greater omentum and the small intestine. (5) Excision of the parietal peritoneum over areas of vareous sizes caused no adhesion. (6) Even prolonged contact between the intestinal wall and normal serosa did not result in the formation of adhesions. However, firm adhesions resulted from prolonged contact between injured serosal surfaces regardless of the type of injury. (7) The author would like to emphasize that large peritoneal defects should be left untreated, because attempts at peritonealization result in additional injury to the subserosa and often in more extensive adhesions. Experiment 2. (1) Edema and an infiltration of leucocytes occurred in the early stages of the inflammation. These histological changes were seen not only in the subserosa, the muscular layer, and the submucosa, but also in the mucosa. Lesions in the mucosa slowly developed into necroses or ulcers. The intensity of the adhesions varied with the severity of the lesions in the mucosa. (2) Twenty-four hours after injury to the peritoneum, P. A. S. positive substances began to appear in the submucosa, disappearing fourth post-operative day. (3) The process of the formation of the adhesions may be outlined as follow: a) After injury to the peritoneal surface, an exudate is formed. b) Thise xudate coagulates to form fibrin, which causes adiacent surfaces to cohere. c) Dunng organization, fibroblasts or fibrocytes migrate into this area. e) Whth the aid of mucopolysacchrides in ground substances, collagen is deposited and grdually a firm adhesion is formed. In some cases, however, this area becomes membraneous or strand-like in form during the completion of the process of adhesions, and is eventually torn apart.

タイトル(別表記) The Effect of Laparotomy (Appendectomy) on Portal Circulaton Time
フルテキストURL 031_005_009.pdf
著者 仲原 泰博|
抄録 Following Ueda-Yasuda's Procedure, the author observed changes on the portal blood circulation time, the body temperature, the blood pressue and the pulse rate of 16 patients (A group, five patients with caecum mobile or appendicitis chronica : B group, six patients with appendicitis acuta non-perforativa : C group, five patients with appendicitis acuta perforativa = appendicular peritonitis). Measurements were taken four or five times: before operation, immediately after operation, on the first, third, and fifth, postoperative day. Portal blood circulation time before operation was significantly prolonged in C and B group as compared with A group. Portal blood circulation time immediately after operation was prolonged in each group as compared with that taken before operation. Postoperative duration of prolonged portal blood circulation time was longer in C group more than in A and B group. Postoperative courses of all 16 patients were good and without postoperative complications.

抄録 I MEDSPECT is a medical mass spectrometer for continuous in-vivo measurement of tissue, blood and respiratory gases. Interfacing catheter for tissue in measurement has Teflon membrane. The permeability and perfusion rate for various gases through its membrane varied with temperature. The temperature coefficient of Teflon catheter in the range of 15℃-40℃ is approximately constant with -2% of correction per degree for oxygen and carbon dioxide. Linear correlation was confirmed experimentally. II The brain tissue gas tensions were measured in ten dogs with intra-venous anesthesia at normothermia and deep hypothermia using perfusion cooling, including circulatory arrest for 30 minutes at 20°C of cerebral temperature. On average, the brain tissue P(O2) was 15mmHg in normothermia when the arterial P(O2) showed 95mmHg and the brain tissue P(CO2) was 49mmHg when the arterial PC02 showed 30mmHg. The brain tissue carbon dioxide tension gradually decreased by cooling and increased during circulatory arrest for 30 minutes; from 45mmHg to 72mmHg. The brain tissue oxygen tension increased during cooling from 15mmHg to 41mmHg and decreased in the circulatory arrest; from 41mmHg to 36mmHg. III The ischemic muscle gas tension was measured in a 22-year-old man, who was suffered from thromboangiitis obliterans bilaterally, and had the popliteal autovein bypass surgery 3 months ago. Control oxygen tensions in the both anterior tibial muscles showed about the same; 35mmHg and 36mmHg respectivelly, and the P(O2) of the non-operated side showed remarkable low level of 18mmHg as compared with the side of arterial reconstruction surgery after 5-minutes ankle exercise.

タイトル(別表記) Applications of critical point drying for scanning electron microscopic study of clay minerals
フルテキストURL pitsr_044_001_006.pdf
著者 野一色 泰晴| 田崎 和江|
抄録 The scanning electron microscopic studies of the clay minerals have usually been made on air-dried samples. The air-drying method is, however, not always preferable for H(2)O rich clay minerals such as imogolite because of their strong contraction in the dehydration process. The present writers examined the critical point drying for H(2)O rich clay mineral (imogolite) and proved that this drying method is excellent in preservation of natural surface of the minerals than that of air-drying. Imogolite which examined was separated from Kurayoshi pumice beds. The samples were treated first with OsO(4) solution and then were dehydrated progressively with ethanol. After completing above treatments, the imogolites which sealed in vessel were dried successively at critical point of CO(2). The samples were mounted onto brass stubs and coated first with carbon and then with Au-Pd alloy. The Japan Electron Optics Laboratory Co. scanning electron microscope Model JSM-50A which was installed in the Division of Rehabilitation Medicine in the present Institute was used at the operating conditions: accelerating voltage 25kV, magnifications ranging from 3000 to 40000. The scanning electron micrographs of the air-dried imogolite are shown in plate I, and cry tical point dried ones are in plate II and III. The former shows twig-like shape which indicated the effect of contractility, whereas the latter exhibits softly curled and entangled threads. The diameter of these threads ranges from 280A to 560A.

著者 野一色 泰晴| 仲原 泰博|
抄録 This is a report of cancer of the stomach encountered in a 71-year-old man who admitted to the hospital with complain of epigastralgia. He had undergo a two third gastrectomy with gastroduodenostomy 24 years before because of severe gastritis. For several years he had ambulatory treatment for diabetes mellitus, which was under good control. Laboratory examination revealed that red-cell count was 4,800,000, white-cell count 11,500 ; hemoglobin was 12.7gr. per 100ml, hematocrit 49.5 per cent. Total serum protein was 8.2%. The stool was positive for occult blood and the urine negative for protein. X-ray studies in barium filled stomach in upright position revealed a filling defect in the lessor curvature side. In the prone and supine double contrast studies, a lesion was visualized of irregular outline with marked surface unevenness. Endoscopically, a rough tumor resembling Borrman Type III cancer was found near the stoma on the anterior wall of gastric remnant. Marginal blending and convergency of the folds showing sudden cessation around the ulcer were recognized as well. These findings led the authors to the diagnosis of the cancer developing in the gastric remnant and total gastrectomy with esophagojejunostomia was performed. Reports of cancer in the gastric remnant detected more than 20 years after the first operation are so small in number.

タイトル(別表記) Fundamental study of post operative intestinal adhesion -Findings on early stage of peritoneal inflammation by ultraviolet irradiation-
フルテキストURL pitser_046_001_009.pdf
著者 野一色 泰晴|
抄録 Early process of peritoneal inflammation on rat by ultraviolet irradiation was studied histologically and scanning electron microscopic· ally. After 1 minute irradiation of ultraviolet, minimal exudation on mesothelium was found. After 15 minutes irradiation, microvillies on mesothelium were covered with exudate. After 20 minutes, fibrin fibers appeared on intact mesothelium. Though the fibers wafted in exudate, the fibers could be cleared up by irrigation of saline. After 30 minutes, white and red cells appeared on the nest of fibrin fibers. After 45 minutes, edema came out at subserosal layer. After 1 hour, mesothelium was covered with fibrin fibers, white and red cells. But the coated fur could be washed off by jet irrigation of saline and intact mesothelium benearth the fur appeared. These results indicate that washing a peritoneal cavity by saline after abdominal operation is of practical value to prevent a intestinal adhesion due to post operative intestinal inflammation. Inflammatory changes of intestinal mesothlium was clearly demonstrated by scanning electron microscope and these observations revealed that scanning electron microscope was very useful for the study of inflammation which occured on the surfaces of organs.

タイトル(別表記) A useful procedure for taking photograph of resected specimens
フルテキストURL pitsr_047_001_003.pdf
著者 野一色 泰晴|
抄録 Histochemical, biochemical, and electron microscopic investigations on resected specimen have expanded in almost exponential manner in the past ten years and taking photograph of the specimens is also of importance for the examination of them. The specimens are, however, damaged during the time of taking photograph by various factors such as heat, dryness, light etc. For the investigations of this kind, the most important requirement for preservation of protoplasmic structure is to interrupt the dynamic process of the cell as prompt as possible and to stabilize the structure with a minimum of change. To prevent the damage of the specimens during the time of taking photograph, the following procedure is proposed: The specimen is dipped into cold saline solution, phosphate buffer, or cacodylate buffer. as soon as possible after operation. Photographic procedure is carried out upon the specimen dipped into the solution. By this procedure, the specimens can be protected from being damaged by heating and drying. Furthermore, the specimen can be preserved in its original shape due to the aid of buoyancy. This procedure has an another advantage : The photograph is in principle free from halation on the surface of the specimens. Thus, the proposed procedure is very useful for taking photograph of resected specimens in general.

抄録 A plasma emission spectrophotometer "Spectraspan" (low power d. c. plasma arc, operating on argon) was evaluated for boron determination in thermal waters. The influence of acids (hydrochloric, nitric and sulfuric acids) and several metallic ions (Na(+). K(+), Mg(2+). Ca(2+)) on emission intensity was studied. There was a linear relationship between emission intensity and boron content from 0 to 500 mg/l. Boron in thermal waters was easily determined by standard addition method. Precision. coefficient of variance and recoveries of known amount of boron added to the sample for 11 repricate analyses were 0.12μg/ml, 2.02%, 95.0-101.7%, respectively. Boron content of 27 thermal waters in the Sanin district was determined. and the highest B content in the sample waters were 8.8 mg/l (Tottori spa) in Tottori Prefecture and 14.6-25.0 mg/l (the thermal springs at the foot of Mt. Sanbe. a non-active quaternary volcano) in Shimane Prefecture. The relationships between B content and water temperature, B content and pH value were not recognized. Significantly positive correlationship was observed between Band Li contents.

抄録 Presented here is a case report of a 56 years old male patient with chronic pancreatitis in which a dramatic improvement in symptoms and objective findings were noted after endoscopic elimination of protein plugs. In September, 1979, he had an acute onset of pancreatitis followed by pseudocyst formation and the following combined operations were performed: resection of the pseudocyst, resection of the body and tail of the pancreas along with the spleen, partial resection of the stomach and the transverse colon, and gastroenterostomy according to Billroth I method. He had been followed up at out-patient clinic for chronic pancreatitis and diabetes until January 14,1979 when he was hospitalized for anorexia, loss of weight, pretibial edema, and upper-abdominal pain. The patient's condition was characterized by emaciation (height 152 cm, weight 37 kg), anemia (Hb 7.9g/dl), hypoproteinemia (serum protein 4.2 g/dl) , and hypolipidemia (total cholesterol 73 mg/dl). Abdominal ultrasound, abdominal CT and ERCP revealed stones in the pancreatic duct. Symptoms and objective findings were only partially improved by medical regimens. Subsequently we performed endoscopic cannulation of the pancreatic duct for elimination of pancreatic stones. Successful elimination of large numbers of protein plugs resulted in dramatic improvement of symptoms and objective findings. This procedure proved to add a new important tool in the treatment of chronic pancreatitis.
